SHOVEL-PLOW.

Specification of Letters Patent.

Patented Nov. '7, 1905.

Application filed May 3,1905. Serial No. 258,709.

To all whom it may concern:

Be it known that I, ROBERT L. BURNETT, a citizen of the United States ofAmerica, and a resident of Hatchers, county of Quitman, State ofGeorgia, have invented certain new and useful Improvements inShovel-Flows, of which the following is a full and clear specification,reference being bad to the accompanying drawings, in which Figure 1 is aperspective view of a plow.

provided with my improvements, the shovel being removed therefrom; Fig.2, a view, partly in side elevation and partly in section, of the same;Fig. 8, a section on the curved line 3 3 of Fig. 2; Fig. 4, a transversesection on the line 4 t of Fig. 2, the shovel being removed; Fig. 5, asection on the line 5 5 of Fig. 2; Fig. 6, a view similar to Fig. 2.,showing an improved turn-plow attached to the plow-foot, the shoe andshovel shown in the other views being removed; Fig. 7, a section on theline 7 7 of Fig. 6, and Fig. 8 a perspective view of the shoe removed.

The object of this invention is to improve and render more durable andefficient that class of cultivating-plows known as shovelplows, as morefully hereinafter set forth.

To the accomplishment of this object and such others as may hereinafterappear the invention consists of the parts and combination of partshereinafter fully described, and particularly pointed out in theappended claims, reference being had to the accompanying drawings,forming a part of this specification, in which the same referencecharacters designate like parts throughout the several views.

Referring to the drawings by reference characters, A designates theplow-beam, a the usual handles attached thereto, and B C the two barsconstituting the plow-foot, these two bars being pivotally clamped attheir upper ends upon opposite sides of the beam by means of ahorizontal bolt 6, passed through the beam at a point nearer its upperedge than its lower edge. The bars B and O lie substantially parallel attheir lower portions, and their upper ends are provided with extensionslettered,

res ectively, B and 0, these extensions curvp ing downwardly andrearwardly to a point below the lower edge of the beam and thenupwardly, these upward-extending portions lying parallel and embracingthe, beam upon opposite sides thereof. These upward-extendingextremities are provided with a series of registering bolt-holes 6,through which and the interposed beam is passed a clamp-bolt 6 this boltpassing through the beam nearer its lower edge than its upper edgethatis to say, at a point below the horizontal plane of the bolt Z). Aseries of holes I) enable the angle of the plow-foot to be readilyadjusted by simply changing the bolt from one pair of holes to anotherpair, and the curved rearward extensions of the plow-foot bars serve tobrace the plow-foot rigidly.

A shoe D is clamped removably to the lower end of the plow-foot, thisshoe consisting of a short front plate cl, lying against the front loweredges of the plow-foot bars and tapering upwardly to an edge, and alonger plate (Z, lying against the rear edges of the plowfoot bars andprovided with a vertical row of holes d, these front and back platesbeing divided by an integral web (Z which is provided with abolt-hole (ZThis shoe receives the lower ends of the plow-foot bars, forming a sortof socket for the same, and it is rigidly but removably attached to thebars by means of a horizontal bolt 5*, which is passed through the barsand the intermediate web portion (Z clamping the bars of the plowfootagainst said web and between the front and back plates of the shoe. Theshovel E is attached to the plow-foot by a bolt 6, which passes throughthe shovel and between the bars of the plow-foot and through one of theholes cl in the back plate of the shoe, the shovel resting against thetapering front plate el and the plow-foot bars and being supportedthereby. By means of a vertical series of bolt-holes cl the device isadapted to receive shovels of various sizes and to permit them to bevertically adjusted on the plow-foot.

In case it is desired to use a turn-plow the plow-shovel and the footare removed and the turn-plow designated by the letter F in Figs. 6 and7 is substituted. This turn-plow may be provided with a removable pointf 2 and a vertical rib f on its rear face, this ribf fitting between theplow-foot bars and being clamped in place by means of the aforesaid bolt6* and a supplemental bolt 0 passed through the supplemental bol t-holesIf, formed in the plow-foot bars and the intermediate above set forthpossesses important advantages. By bending the upper portions of theplow-foot bars in the manner set forth the plow foot is materiallystrengthened and braced and will require but one bolt 6 to provide forits adjustment. Thus bowing the standard extensions downward andrearward has the further advantage of bringing the preponderance ofweight at the rear end of the beam, where it will be in a betterposition to permit the plowman to control and guide the plow. and thiscontrol of the plow is facilitated by attaching the handles to the beamat a point between the two bolts band if that is, within the bowedportions B of the standards. By arranging the bolts 5 and I) out ofalinement the beam is rendered stronger than if the bolts were arrangedin the same horizontal plane, as is obvious. The shoe or rub-ironprotects the point of the plow-foot against wear, the front plate (2'acting as a sort of washer to receive the wearing action or thrust ofthe "plow-shovel. This shoe or rub-iron may be inexpensively made andits use will make the plow-foot last indefinitely if the shoe bereplaced by a new one in time.

My improved plow-foot may be attached to any ordinary plow-beam now onthe market and is adapted to receive any kind of plow that may beattached by the usual heel-bolt. It will be seen also that my plow-footis adapted to receive a turn-plow of the improved form shown anddescribed by simply removing the rub-iron.

It will be apparent to those skilled in the art that various mechanicalembodiments of the invention are possible, and I therefore do not wishto be limited to the exact arrangement and construction shown.

WhatI claim, and desire to secure by Letters Patent, is

1. In combination with a plow-beam, of a plow-foot consisting of a pairof bars embracing the beam at their upper ends, a transverse boltpassing through the bars and the beam, said bars having their upperextremities bent rearward and downward below the beam and then upwardacross the rear end of the beam, these upper extensions embracing thebeam and being provided with a series of holes, another bolt passedthrough a pair of these holes and the intermediate beam, and handlesattached to the beam at a point between said two bolts, substantiallyset forth.

2. In combination with a plow foot or standard composed of a pair ofseparated bars, of a rub-iron or shoe attached to the lower endsthereof, said shoe embracing the lower ends of the bars and having arear extension extending upward along the back of the plowfoot andprovided with a vertical series of perforations, and a plow-shovelbolted to the front of the plow-foot, its securing-bolt passing backthrough one of the perforations in said upward extension.

3. In combination with a plow-beam and a plow foot or standard, of arub-iron or shoe detachably attached to the lower extremity of theplow-foot, said rub-iron consisting of a socket embracing the lower endof the standard, a part (Z of the socket extending upward and lyingagainst the front of the plow-foot and another part (Z extending upwardand lying against the back edge of the standard and provided with avertical series of perforations, and a plow-shovel lying against thefront part (6* and having its securing-bolt passed through one of theperforations in the rear part, for the purpose set forth.

4. In combination witha'plow-beam carrying a depending plow-foot, thisplow-foot comprising a pair of separated bars, of a rubiron embracingthe lower separated ends of the plow-foot and consisting of a front partd" lying against the front side of the plowfoot, a rear upward extension(Z provided with bolt-holes, and a connecting Web portion (Z lyingbetween the separated bars of the plowfoot, a bolt passing through thebars of the plow-foot and a web portion, and a plowshovel lying againstsaid front part (P and having its securing-bolt passing between the barsof the plow-foot and through one of the holes in the upward-extendingpart (Z, substantially set forth.

In testimony whereof I hereunto affix my signature,-in the presence oftwo witnesses, this 1st day of May, '1905.
